Hello, Microsoft Technical Team:

I would like to report a potential issue with File History after installing KB5101684 on Windows 11.

Before installing KB5101684, File History worked correctly; after the update, even after modifying files and confirming successful saving, the backup version history and timestamps in the File History interface may not be updated.

Currently confirmed:

• The backup drive (D:) is connected correctly.
• File History is enabled.
• The File History Service is running normally.
• The backup location is set to the local D: drive.

1. The problem is described as follows:
2. After modifying Word documents and images, the files are indeed copied to:
3. D:\FileHistory\user\LAPTOP-GJTRIQFJ\Data\C\Users\user
4. However, in the "Restore Personal Files" interface, the new backup version date does not appear; it still displays the old version date (e.g., 2026/7/28).
5. After executing "Execute Now," the last backup time displayed in File History is still not updated.
6. Only after re-entering the console:
7. Console → All Console Items → File History → Select Drive

and selecting the same backup drive again will a new backup version be created, and File History will return to normal.

This issue began occurring after installing KB5101684; it did not appear before the update, and File History settings were not modified.

We hope the Microsoft technical team can assist in confirming:

Whether KB5101684 affects the File History version indexing or backup status update mechanism

Whether it is necessary to correct the issue of the timestamp displayed in the File History UI being out of sync with the actual backup status

If it is confirmed to be related to KB5101684, we hope that this issue can be fixed in the subsequent August security update to restore normal File History backup and version restoration functionality.

Thank you to the Microsoft team for assisting in investigating this issue.

Hello,

Thank you for the detailed testing. Based on what you described, this does look more like a File History status/indexing issue than an actual failure to copy the files.

KB5101684 does contain changes related to File History, specifically a fix for automatic backups to SMB network shares. However, Microsoft currently states that there are no known issues with KB5101684, and I could not find an official acknowledgement yet of the local-drive File History behavior you described.

Since the files are actually being written to D:\FileHistory but the “Restore Personal Files” view and “Last backup” time remain outdated until the same drive is selected again, your findings are useful evidence of a possible regression.

For now, I would suggest:

1. Continue using “Select Drive” and re-selecting D: as a temporary workaround.
2. Submit this behavior through Feedback Hub (Win + F), preferably under Files, Folders, and Online Storage > File History, and include the KB number and your reproduction steps.
3. Since KB5101684 is a preview update, if this problem is affecting regular backups, you can also uninstall KB5101684 temporarily and check whether File History immediately returns to normal.

At present, we cannot confirm that Microsoft will include a fix in the August security update until Microsoft officially acknowledges the issue, but your reproduction steps strongly suggest that this should be investigated as a KB5101684 regression.
